The Scott County Sheriff's Department found the body of a man at a home in the 500 block of West Main Street in Austin Tuesday night.

According to the probable cause affidavit, suspect Robert Riley Jr. admitted the remains belong to Paul Graupe, who was last seen on Thanksgiving Day 2009.

"Riley confirmed that the remains that were found were that of Paul Graupe and that he concealed the remains in the apartment," said Scott County Sheriff Dan McClain.

Riley, 39, admitted to stabbing Graupe in the back and sealing the body in the apartment, according to the affidavit.

The sheriff has requested to continue the initial hearing for up to 72 hours to get everything together, meaning Riley has not been officially charged yet.

Police won't say exactly where the body was found, but neighbors said they saw deputies tearing up the floorboards in a small building behind the main house on the property.

Investigators said Riley had been a suspect in Graupe's disappearance for some time but they could not prove it.

"We had no murder weapon. We had no body. We had no firsthand witnesses and we had no secondhand witnesses to this case," said McClain.

The victim's family says Riley owed Graupe money.

"Paul, out of his own kind heart, loaned him (Riley) some money and then Paul was always, 'I'll loan you a few dollars, but know you're going to pay me on Friday when you get paid' and he was looking for his money,” Graupe's brother, Hugh Pasley said.

Family members are still confident Riley is innocent.

“I just can’t say he did. I just don’t see it you know,” said Riley’s aunt, Judy Riley.

Judy Riley said she can't believe what police believe her nephew did.

The sheriff said his department got a tip on the case Monday afternoon and got a search warrant for the property.

Police said it appeared the body had been hidden beneath debris for a long time.

That is a very frustrating fact for the victim’s brother, Hugh Pasley.

“That is one of the hardest things. Murdered, but to be laying there for three years? That's hard to take. Two blocks from his own house,” Pasley said.

Riley has been charged with nonsupport in a separate case and is being held without bond.

Diplomats and negotiators kept working Tuesday as a deadline approached to reach a deal on a framework agreement on Iran's nuclear program, but a U.S. State Department official said the discussion may continue after the cutoff.
